Some science and technology projects are just plain large

Some science/technology is big news like the discovery of a new gene – but sometimes its just big, like the Saturn V rocket of the Apollo era. Here we take a look at pictures of some recent BIG science and technology topics like a cool new wind turbine, a black hole discovery and more. Have fun:

Shell, which is the replica of the biggest detonated Soviet nuclear bomb AN-602 (Tsar-Bomb), on display in Moscow, Russia. The shell is part of an exhibition organized this summer by the state nuclear corporation Rosatom.

Markarian 231, a binary black hole found in the center of the nearest quasar host galaxy to Earth, is seen in a NASA illustration. Like a pair of whirling skaters, the black-hole duo generates tremendous amounts of energy that makes the core of the host galaxy outshine the glow of the galaxy's population of billions of stars, according to a NASA news release. Hubble observations of the ultraviolet light emitted from the nucleus of the galaxy were used to deduce the geometry of the disk, and astronomers were surprised to see light diminishing close to the central black hole, said NASA.

The main engines of the space shuttle orbiter Discovery are seen on display at the Udvar-Hazy Smithsonian National Air and Space Annex Museum in Chantilly, Virginia August 28, 2015. Shuttle Discovery was in service for 27 years and flew 39 times before being retired in 2011.

The shock wave of a T-38C supersonic jet flying over the Mojave Desert in California. Researchers used NASA-developed image processing software to remove the desert background, then combined and averaged multiple frames to produce a clear picture of the shock waves.

David Yanez stands beside a 6-metre (20-ft.) prototype of a wind turbine without blades in a countryside at the small village in Gotarrendura, Spain, June 2, 2015. The windmill works by spinning air whirlpools in the inverted cones, aided by magnets, to create patterns of oscillation that are converted into electrical power by a generator. The same phenomena is responsible for the 'singing' of suspended power lines in the wind.

An employee works on a reflector covered with molybdenum and gilt grids for a heavy class space satellite at the large-sized transformed mechanical systems center of the Reshetnev Information Satellite Systems company in the Siberian town of Zheleznogorsk.

NASA's Curiosity Mars rover is seen at the site from which it reached down to drill into a rock target called 'Buckskin' on lower Mount. The selfie combines several component images taken by Curiosity's Mars Hand Lens Imager (MAHLI) during the 1,065th Martian day, or sol, of the rover's work on Mars, according to a NASA.

Xing Yile (L), a 26-year-old middle school art teacher, works with his friend on their homemade replica of the "Hulkbuster" Iron Man armor from the movie "Avengers: Age of Ultron", at an underground parking lot in Zhengzhou, Henan province, China, May 12, 2015. The 3.4-metre-tall replica is made of over 100 fiber-reinforced plastic components. It took Xing and his friends two months to put them together after watching the trailer of the movie this past March.

People view the High Altitude Cherenkov Experiment (HAWC) observatory during its inauguration on the slopes of Pico de Orizaba and Sierra Negra, near Puebla. Sitting at the foot of a volcano in Mexico, this facility looks like a water treatment plant. In fact, it's one of the largest and most powerful observatories ever built on Earth. Unlike optical observatories that use telescopes to study planets and stars, the HAWC detects high energy cosmic particles to unravel the mysteries of black holes and supernovas. HAWC is able to track where gamma rays originated, no matter how many light years away.

Visitors explore the world's largest playable guitar, part of a new exhibition from the National Guitar Museum "Guitar: The Instrument That Rocked The World" on display at the Liberty Science Center in Jersey City, New Jersey. The 45.5 foot (13.87 meters) long 2,255-pound (1,023 kg) copy of a Gibson Flying V guitar was built by students at the Academy of Science & Technology in Houston, Texas in 2001.

The 10-m (32.8 ft) South Pole Telescope and the BICEP (Background Imaging of Cosmic Extragalactic Polarization) Telescope at Amundsen-Scott South Pole Station is seen against the night sky with the Milky Way in this National Science Foundation picture taken in August 2008. Astronomers announced on March 17, 2014 that they had discovered what many consider the holy grail of their field: ripples in the fabric of space-time that are echoes of the massive expansion of the universe that took place just after the Big Bang. The gravitational waves were detected by the BICEP telescope.

This NASA's photo of Pluto was made from four images from New Horizons' Long Range Reconnaissance Imager (LORRI) combined with color data from the Ralph instrument in this enhanced color global view released on July 24, 2015. The images, taken when the spacecraft was 280,000 miles (450,000 kilometers) away, show features as small as 1.4 miles (2.2 kilometers).

A supermassive black hole with millions to billions times the mass of our sun is seen in an undated NASA artist's concept illustration. In this illustration, the supermassive black hole at the center is surrounded by matter flowing onto the black hole in what is termed an accretion disk. This disk forms as the dust and gas in the galaxy falls onto the hole, attracted by its gravity.
